Power supply upgrade

[old_geekster]

@roadkill37, this is unfortunate!  The proprietary PSU is something that HP started with certain models.  It does make things a bit difficult.

@roadkill37,

Just out of morbid curiosity: are you sure the 500 watt PSU (L05757-800) doesn't fit OR can't be made to fit (especially with a little persuasion/ingenuity) inside your HP Envy Desktop TE01-1244's chassis?

[roadkill37]

I have to be honest and say I am not 100% sure the 500 watt psu won't fit. I kind of judged things by pics Ive seen of both of them online. The 500 seems bigger than the 400 from what Ive seen. Not knowing the exact measurements of the 500 and not knowing whether or not it will fit for sure I'd hate to gamble with the kind of money they want for it and have it turn out that I can't use it. I was hoping to upgrade to a 1650 GTX that I have in another pc that just crashed. That's a pretty big card itself.I did check to make sure that fits and it does but don't have much more play room if I have a bigger psu

@roadkill37,

All right, I picked up the proverbial torch and contacted "AA2Z Supply" based in California (1-800-[see website for toll-free number]).  I spoke with a very knowledgeable person named James, and he said he had a 400 watt HP power supply in stock he claimed would fit in your HP Envy Desktop TE01-1244.

If you were to purchase this online (see link below), you would have to place the order for an "HP L05757-800" BUT in the comment section you would mention that you want the 400 watt "HP L05757-400" power supply for HP Envy Desktop TE01-1244.  Same pricing as the L05757-800: $175 -free shipping.

Hope this helps.

I really appreciate you taking the time to look into it for me. I think I'm just going to stick with what I have and cut my losses. You said they told you they had a HP LO5757-400 in stock but the HP part number for the 400 is actually L069242-800. I just can't take the risk of spending that kind of money just to cross my fingers and hope it's the right one. I really wish I could find someone who can tell me the actual dimensions of the 500 watt in the HP store.

or I could just order the 500 and install it without putting the side back on my case and have it just sit there LOL

@roadkill37,

Yes indeed: you could park your PSU (or secondary PSU and GPU as seen here) outside your chassis:

See my HP EliteDesk 800 G3 SFF upgrade thread here: https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Upgrading-HP-Elite...

ok one more question.Sorry I'm not very pc hardware technical at all lol. I do have a brand new 450 watt evga power supply that I bought with the computer that I thought would fit like it would inside a pavilion. Can I just use this one externally if need be ? Like I said in previous post I could always try to just remove the side of my case and set power supply next to it on the outside somewhere.

@roadkill37,

No worries, I too hey-ho am learning while I go.

Perhaps you want to browse through my HP EliteDesk upgrade thread to see what can be done to assist an HP PC to power an upgraded GPU.

I assume your GTX 1650 does not have/need a 6- or 8-pin 'supplementary power connector'.

If it did, then the solution would be easy-peasy: connect your 450 watt evga power supply's ATX 24-pin to an ATX 24-Pin to SATA Power Supply Adapter, connect the adapter's SATA input to one of your primary PSU's SATA power supply connections, and lastly connect one of your evga's 6- or 8-pin PCIe power cables to power your GPU. Done.

What that setup will do for you is that you keep your primary power supply where it is and what it is supposed to do, but the SATA to SATA power adapter connection cable will daisy chain aka synchronize your evga PSU as a secondary dedicated power supply to power your GPU.  Whenever you power up your PC, it will automatically power up your secondary PSU and thus immediately power up your GPU without causing any sort of electrical system misalignment or unbalanced power issues. And vice versa, when you power your PC down, the secondary PSU will smoothly power down in tandem.

But since your GPU is solely PCIe X16 slot (75 watt) powered, the solution is moderately more complicated.  In addition to your evga PSU, you would have to park your GPU outside your case also -for the how's and what's, please see my EliteDesk 800 G3 SFF solution to make much larger/powerful GPUs work which are otherwise too massive to fit inside the SFF chassis.

I'm not sure you want to go that route, because the price tag for the additional parts and bits you need to do what I did would far exceed what it would cost you to buy the aforementioned proprietary HP 400 watt PSU.

Conclusion/my pennies' worth: it may be worth-it to consider buying that $175 power supply.

Lol no clue what you are saying but anyways I did notice the evga I have has the 24 pin connector for the motherboard but my desktop does not have a connection for it. So yes it looks like I have to go with an HP proprietary one. But as I mentioned before the part # the guy you talked to gave you for the 400 watt doesn't match HP's part # for that one.The 500 watt part #'s match but not the 400 so I'm not taking a 175 $ chance that it's definately the right one.
