Nah, too cheap for a PSU - only stick this in a machine you don't care …Nah, too cheap for a PSU - only stick this in a machine you don't care about


OMG, this is actually a very decent PSU for the money, ideal for a budget build.

It's EVGA. Top tier for PC hardware.. Imagine actually thinking otherwise.

Long term higher psu will say you ££ and give you leg room to change about parts. Always check reviews. Bad PSUs can ruin system very easily.



Rubbish .. only buy what you need .. invest the money saved and earn loads. Lower wattage PSU in a low power computer will also save electricity as you are more likely to be running at an efficient part of the power curve.
PC components are getting more and more energy efficient .
BUy bigger if you know you are getting more power hungry parts in the future, but 450w should be enough for most budget computer builds 1xcpu +1GPU.
Postage is a significant portion of the price 25% .. maybe look on ebay for the same thing? (unless you like paying for his D I V O R C E and his starship)

This is a quality PSU for entry level builds and is very well reviewed as well. I am surprised by the price as that is probably a black friday deal.

What a deal though. Hot.

That's real nice. Even with a decent 6 core and an upper mid tier GPU this is all you need.

Rated Tier D on the LTT PSU Tier List.. I wouldn't be putting anything expensive in the same machine as it

I hate to be that guy. This "BT" is a D Tier. This isn't a top tier PSU and below average on the reliability scale.

OOS now, great price.

Seems to be shooted up to £45+

EVGA bronze power supplies are known to be a bad investment. It doesn't matter how cheap a psu is you don't cheap out on a psu when they're known to have issues, it's that simple

Did I not say, buy a better psu for the future..

And if you're going to worry about electricity's youd buy gold certified not bronze. Alot of PSUs have feature like the fans won't turn on unless it requires to pull more. Similar to what GPUs do.

Lastly, if you're talking about investing, why bother with a pc. You can trade stuff on your phone. Unnecessary to buy a 300-400 pc for investing then worrying about electricity.
Still at £19.99 for me.

My rig only needs 125w. Cheap emu rig from spare parts, don't need to expand. What PSU would you advise I should get?

Are you planning to upgrade any time soon? Look into seasonic, be quiet, Corsair rm, Silverstone etc.

Can't really give you advise with little information.

Sorry.

Say you have a standard 6-8core CPU with midrange GPU which draws 250W at load (pretty standard figure). It will probably idle around 70-100W.

That efficiency figure that you see quoted is based on 50% load. Once you draw less and less of that capacity, the efficiency plummets.

Here is a graph for a 1000W PSU.

39141482-HCQhc.jpg
There is absolutely no point in buying much higher other than one specific unique case.... If you require silence. That 1000W PSU if designed right will have a idle-stop fan and run in complete blissful silence most of the time.... inefficiently.

With regards to future proofing. Look at NVIDIA and Ryzen. The trend is using less wattage year by year, not up. Turing is the most efficient and most expensive GPU line ever created, meaning SLI/Crossfire setups are a thing of the past except to those with unlimited budgets. AMD can push out 16 cores with a TDP of 100W.

I'd welcome your thoughts. Happy to discuss in a logical way. Sorry for the original bluntness.

That image from guru3d I believe, shows total system loaded wattage rather than CPU wattage.

As you see, even with 3950x which is 16C/32T, you are at 220W with all 16 cores loaded. That's also with a very hungry Vega 11 GPU (likely not loaded for the graph mind you).
