Bad quality 500w psu good enough for GTX 1070 ti?

[onni313]

Is it bad to use my PSU (Silverstone 500W, Strider Essential-230, 80 Plus) for a GTX 1070 ti? I know the recommendations, but there is a big difference between a high quality and bad quality PSU. Im asking for answer from a professional, is it 100% safe to use my PSU? Could it harm my other parts? I've tried the wattage calculators. I will buy a new psu, when i can.

Btw, here is the specs if someone needs them
CPU: Intel Core i7 4771 @ 3.9GHz (Yes, with all cores)
GPU: EVGA GeForce GTX 1070 Ti SC GAMING ACX 3.0
RAM: 16GB Kingston HyperX Fury @ 1866mhz (4x4)
SSD: Samsung 250GB 850 EVO
Mobo: AsRock Z97 Anniversary
CPU Cooler: Cooler Master Hyper T4
PSU: Silverstone 500W 80+ Strider
3 case fans

Its not a bad PSU, but not an amazing one either. It is a bit old but should be fine, its better than alot of other power supplies we see people using on here.

You're right with that.

This PSU is not noted as blacklisted, SilverStone have quite good reviews 😉
You should be fine to use this PSU, keep in mind that sometimes bad units happen even in the "good" psu manufactors.

To be completely honest and objective it is a bad PSU.

Why is it a bad PSU you ask?

Because it is only rated to 80 Plus, like not even metal ranking.

https://en.wikipedia.org/wiki/80_Plus

80 plus is basically an attendance award for being able to make a functional power supply.

If they went any lower then they would lose the entire certification.

The 80 Plus rankings are based on efficiency.

The more efficient a power supply the less heat it creates.

Power supplies hate heat, in fact most electronic devices hate heat.

Running an 80 Plus power supply at any significant fraction of its maximum wattage is just asking for trouble.

Most time 300-400 watt 80 Plus power supplies are put in OEM computers with integrated graphics where the maximum wattage isn't taxing enough to generate enough heat.

A geforce 1070Ti has a maximum TDP of 150 watts and lets say the rest of the system comes out at 100 watts, for a total of 250 watts.

Your peak wattage is already at half the rated maximum wattage for the cheaply built power supply.

It's low end and group regulated PSU. So yes, it isn't good for your components and I wouldn't use it for a high end GPU like yours because it does decrease the lifespan.

I wouldn’t use a 500W PSU with a 1070, especially because It will too weak to effectively work with it, you may notice power cuts if you go forward with it.

Honestly I think a 700W is effective for a 1070.

Do you know how much your computer really consumes? No where near what you’re thinking.

Even a GTX 1080ti system + 8700k OC will average ~330w at load, at peak maybe 400w. Very very unlikely to reach 450w, but even if it does it would be fine because a good 500w power supply is rated for continuous use at 100% load.

Wattage isn’t the issue here. It’s the power supply quality. And getting a crappier 700w psu will only add more problems.
