400W okay for i3 4130 and HD 5870?

[i_got_laid_by_a_dragoness]

I've got an older 400W Dynex unit that tested O.K under load. I know that the HD 5870 can use up to 300W or more when overclocked. The i3 4130 uses 55W and I am planning a BCLK of 104, bringing the i3 to 3.5GHz.

 

Based on numbers I should be fine and don't want to spend extra money. Should I get a 500W unit just to be safe? Usually I go with my judgement and would get a better PSU but I want to spend the money on a used GT1030 for a relative.

Yeah I think 400W should be good to go.

 

Makes sense about your money issues.

That sounds like a lowest quality, overrated PSU.

So I'd replace it.

Yes, 400W would be enough, but some don't have the neccessary connectors...

 

But you should get a good quality one!

Dynex PSU? Hard pass. I doubt that thing can actually provide 400W. Definitely would not power a 5870 with it.

 

The i3 can only be BCLK overclocked on a Z87 or Z97 motherboard, just FYI.

And that only with older BIOS versions.

 

They locked it on newer ones, AFAIR...

Yeah yikes, don't with that. That PSU has reviews on Amazon from 8 years ago and I doubt it could output anywhere near 400W back then, let alone now.

Congrats, you got 150 MHz out of your i3? At the expense of a super unstable SATA and PCIe bus...

According to UL Database Search its Huntkey. And they have some really awful/bad stuff....

 

And looking at the Label proves me right -> 30A/3,3V and 28A/5V.

Thats garbage and ancient.

And then two 12V rails with 14 and 15A or 168 and 180W....

And because its an old one, I'd assume the 180W are for the CPU, the 168W for the rest.

 

 

And how much does the HD5870 consume??

 https://www.techpowerup.com/reviews/ATI/Radeon_HD_5870/28.html

 

212W maximum.

 

 

So no, that PSU is garbage and ancient....

so about 375 watts for that PSU? Damn, I'll just get a CX430

Keep in mind the Radeon HD 5870 requires two PCI-E 6-pin connectors.

The "green labelled" CX 430 only naively comes with a single 8+2 pin connector  (e.g. can either be used as a 8-pin or 6-pin PCI-E connector).

You are short one power cable.

 

The newer CX450M has two PCI-E 6+2 pin connections.

The older CX430, and CX450 only has a single PCI-E 6+2 cable.

I made my own 6-pin splitter. As a matter of fact I usually just solder on parts I need to PSUs that don't have them.

 

This is an old 350W power supply that still works phenomenally well, I use it for testing motherboards. The unsleeved MOLEX cables and 4-pin EPS connector really bothered me so I converted two of the MOLEX cables to SATA, one with two connectors and the other with three, and replaced the 4-pin with a 4+4 pin connector. The third MOLEX cable had a floppy connector so I just got rid of it and soldered on two individual sleeved MOLEX cables. The only cable that isn't sleeved is the ATX power connector and I really didn't have the patience that day to solder 20 pins and an additional 4.

Get some knowledge about PSU and what you are doing first.

Because what you are doing doesn't seem to make sense or be up to regulation.

What you are doing is making a bomb/Fire Hazzard...

There is so much wrong with that...

The solder you us, the narrowing of the cable.

Quality of the PSU...

 

And it just doesn't make sense. you haven't gained much...

I gained extra SATA connectors and a 4+4 pin EPS connector. It works fine. And having those thinner cables is fine because they are short and don't need to carry electricity very far; they can handle  300W 50A according to the sleeve.
