Conclusion:
Overall the Ultra LSX 750W PSU is a great power supply at a great price. I have seen a lot of power supplies in this price range and very few of them had the amperage that this bad boy puts out. 58 Amps on one 12 v rail is nothing to scoff at. Normally I will admit I like more than one 12V rail in this case, at this amperage, this powers upply should do everything you need it to right out of the box.
Would I recommend this power supply? Yes, if you are in need of a budget friendly PSU look no further than the Ultra LSX 750W Power Supply
Pros:
- Price
- 12V Rail Amperage
- Not Cheaply Built
- Nice Looking
Cons:
- 12V Rail Might be a Draw Back for Some
