Power supply units come in different wattage. So you should check out compatibility and buy a unit that can power your PC effortlessly. Today we’ll look at the best 600W Power Supply in the market.

You’re strongly advised against buying a cheap power supply – but getting an affordable PSU doesn’t mean you have to sacrifice on quality.

The point of our rhetoric is – your Power Supply Unit is the heart of your PC. Its job is straightforward but vital to the life of any computer. That’s why you need to choose yours wisely.

What a PSU does is covert high-voltage [wall] AC power to low-voltage DC power which in turn fires up your components.



So, to avoid dangerous power surge which could harm your PC’s vital components such as RAM, CPU, and motherboard, you need a quality and efficient PSU.

The Thermaltake Toughpower GX1 isn’t so popular in the market mostly because of its wattage [600W] and it’s a non-modular power supply unit. But it does pack a powerful punch.

This Thermaltake PSU isn’t just a 600W, its maximum output capacity can reach the 720W peak. The input frequency range stands at 47Hz-63Hz. The efficiency rating of this PSU is 80 plus Gold which spells a minimum rating of 90% at 50% load.

The Toughpower GX1 has RGB lighting, which comes preinstalled with a 120mm hydraulic dynamic bearing fan. Impressively, this fan isn’t loud.

This PSU sports a compact form-factor measuring 140mm x 150mm, with multicolored wires adorning the machine. This is something we’re being forced to accept with non-modular PSUs.

The Thermaltake ToughPower is an impressive PSU. It has good efficiency rating, sports a cool and compact design, and is adorned with ATX 20+4 pi, 4+4, PCIe 6+2 and SATA cables and connectors. Nearly everything checks out with this unit.

Don’t mind the name, the FSP Dagger is a nice PSU in the market. The brand FSP, though unpopular in the PC market, is well-known in the SFX market.

The FSP Dagger 600W earned rave reviews when it debuted a couple of years ago. The unit is even 80 Plus Gold certified. And it’s a fully modular CPU with lots of interesting features to discuss.

For efficiency, this unit hits 90% at 50% load. It uses an LLC resonant converter for better efficiency. Given its VR-ready, it can power a gaming PC without hassle.

It has two auxiliary PCIe power connectors and a singular SATA four-pin connector (we expected more).

It’s equipped with Over Power protection, surge protection, and Over Voltage protection. But it doesn’t feature UVP (Undervoltage Protection). However, it has a single +12V rail which comes handy for overclockers.

The [fully-modular] cable management and design of the FSP Dagger is cool. And we can only commend the efficiency and cooling. But we think it’s a little pricey for what it offers.

The EVGA 600W BQ is a good choice if you’re building a new mid-range gaming rig or PC. This unit gives you plenty of value and comes at a great price.

The EVGA 600W BQ comes with a sturdy build, boxy/cubic design, sporting a dark-brown case. It has 80+ Bronze certified power efficiency which means you’ll get up to 85% efficiency at ≥20% load.

This PSU endears itself with all the heavy-duty protection you want – like Under Voltage protection (UVP), Over Voltage Protection (OVP), Over Power Protection (OPP), and Surge protection.

For connectors, it has 2 x 8 PCIe pin connector, 1 x power 24 pin with detachable 4 pin section, 6 x 15 Serial ATA power pin, and 1 x 4 mini-power connector.

The fan is 120mm and it uses a dynamic fluid bearing. This fan makes no noise, thereby giving you a silent PSU. This is a standard ATX sized PSU and should fit into any ATX case that uses an ATX power supply.

The EVGA 600W ATX PSU will give you great power efficiency and performance. It also comes at a competitive price. With a modular design and other cool features, it’s certainly one we can recommend.

The Apevia ATX-JP600W is one PSU you should check out if you’re building a budget gaming PC. The unit can handle ATX form-factor motherboards and is 80 Plus Gold certified to provide good efficiency (≥86%) and performance.

The design of this PSU has no drawbacks. With a shiny black compact case and a brilliant blue thermally-controlled light coming from the fan, this unit catches the eye immediately.

The Apevia JP600W supports ATI crossfire and NVIDIA SLI. It has Over Voltage and Under Voltage Protection as well as Power surge protection. It features four SATA connector pins, 4+4 and 2 x 8(6+2) PCIe connector pins.

The Apevia JP600W isn’t the toughest PSU here, but it certainly makes a statement of efficiency and performance, despite its pint-sized form-factor. This is one PSU that delivers the goods required for its category. Take another look.

We conclude our review by looking at another Thermaltake PSU – this time it’s the Thermaltake TR2 600W. It’s clear Thermaltake is the leading brand in the PSU market. They’ve certainly made their mark.

The Thermaltake TR2 600W is one of the few non-modular PSU we saw with good cable management. It sports a 120mm fan. The input frequency range stands at 47Hz to 63Hz. It has 4 x 4 and 2x 6+2 PCIe connector pins. And there’s 6 x 5 SATA Pin connectors.

This PSU is 80 PLUS Bronze certified and Haswell. It’s not an 80 Plus Gold certified PSU. It still clocks over 80% efficiency at 50% load.

The design of the Thermaltake TR2 600W is compact, with a black case shielding the internal components.

We think highly of Thermaltake products and this one didn’t disappoint. Although in terms of efficiency they could’ve done a little better. This 600W is a big boy that can handle whatever you throw at it; inasmuch as you don’t break compatibility rules.

The importance of Power Supply Units cannot be overemphasized. In fact, they’re the life source of any PC. Their price range largely depends on Form-Factor and the power demands of the PC component.
