Is there something wrong with my new PSU?

[Pomfrit]

Hello everyone im new here. Wanted to ask some thing about my new psu... today i bough a cooler master masterwatt 450w and it gets pretty hot when i touch it... also it doesnt seem to blow out air in the back when i put my hand then.... im worries it will overheat.. also the fan starts spinning only when gaming and still it does not blow put air at rear of my pc... also my cpu and mobo temperatures are a bit higher now... i hope everything is ok with my psu, is it normal that i cant feel the air at rear side? Also when i touch the case at the top its warm... sorry for my bad english, also this is my first post, dont get mad at me

That's normal for any modern PSU.....

Power Supplies (Or most parts with a fan) have a thermal limit. Once that part hits a certain temp, the fans engage (Or spin faster) and start to get it below that limit.

How's your airflow through the PC? And what kind of temps are we talking? Is there anyway you could upload a pic of the inside of your machine?

I will upload a picture when im home. At full load my cpu had 60-62 degrees now it has like 65-66..

mobo has too like 2degrees more... gpu is same exept its a bit louder now maybe...

never had problems with temperatures before.

 

i have 1 front fan

1rear fan

psu fan

2gpu fans

and stock cpu fan

 

temperatures were always the same , but today when i installed my new psu i get a bit higher temps

 

my specs: i5 2400

gtx 1050 ti

16gb ram

1hdd, will soon buy ssd

That's totally fine. An increase like that would be normal. From what you've described about your PSU, it sounds like normal behavior. If it is a bit warm to the touch, the added temps to your overall system would be explained like that. Anything that heats up the air inside your case will have that effect. What I'd recommend would be a second fan on the front of your case to pull that fresh air in and another fan on the top slot of your case pushing out. That would probably be a rather big impact on your temps.

 

Additionally, I'd 100% recommend an aftermarket cooler for your CPU. That'll help too! Noctua makes some great stuff that fits in just about everything.

What case?

 

Where is the PSU mounted and how is it oriented?

Case is normal nothing special it can have 1 front fan and one rear... and i have 6fans overall like mentioned above.

i have the psu at the top in the back side(normal i guess) and the fan is oriented downwards

Ok.  So, those older cases are horrible for using PSUs with "Zero RPM fan modes" because they're designed to have the PSU as part of the ventilation system.

 

The PSU fan is only going to turn on when the PSU gets "too hot", but there's still hot air rising into the PSU from your other components.

 

You really should have a PSU that has the fan run all of the time or a case where the PSU mounts on the bottom with the fan facing down.

 

Cooler Master engineered that PSU to be used in a case where the PSU is mounted on the bottom with the fan pointing down.

So its top mounted - did you orient the install so that its pulling air out of the PC as an exhaust ?  I.E. the fan shouldn't be mashed up against the top of the case, it needs to be pulling air up and out of the computer.

Its at top of the case in the back side and yes its faced down so it exhausts air out of pc

Do nothing, you are fine   If there is an issue it will just shut itself off.  Then you should come back and say now what (unless willing to replace the case)

But the problem is that it blows (exhausts)so little at the back that i can almost to not feel it when i put my hand there

Its not a problem, really.  Because if it got to hot the PSU fan would then spool up completely to cool it back down.  Or it would shut down if it was a critical something (which is unlikely)

 

There are no problems, just thermals.  Take a pic of your PC with the side panel off, lets check your airflow - improve that and problem solved.

This makes me feel better lol... i dont think there is much to improve about my airflow... all i can do is speed up my front and rear exhaust fans and buy a new cpu cooler and thats it i think.. imma upload a picture tomorrow.

My front fan is from be quiet and rear is from arctic so they are both pretty quiet

Sounds good, the proper fans (if you have stock ones they are likely meh at best) you can run them very aggressively and still preserve silence.  For this I prefer (and run) Arctic P12's (14 running at max RPM within 3 feet of me, its a pleasant slight tone)

Ok will try ramping them up a bit and will come back with a picture, cheers

Maybe i should add that i have a i5 2400, gtx 1050ti 16gb ram, 1hdd and will soon buy ssd.

It's a PSU with a fanless mode that's only going to spin based on the PSU temperature, not the PC temperature. That's why I have my concerns.
