PUTORSEN Under Desk PC Mount for Standing Desk with 65×45mm Legs

What it is and what it solves

This PUTORSEN under-desk mount is a clamp-on holder designed for desks with 65×45mm legs. It provides a stable, open-air mounting point for a PC tower, keeping the computer off the floor to reduce dust, moisture and potential bumps from foot traffic. It’s a straightforward way to tidy a workspace and protect a computer from common desk-bottom risks without drilling into the desk itself.

Key considerations before you buy

On paper, the product is compatible with desk legs sized at 65×45mm and supports PC towers with widths from 5.7" to 9.84" (145–250mm) and depths up to 19.68" (500mm). It’s important to measure your desk legs and your tower to ensure a proper fit. If your legs or tower fall outside these dimensions, this mount won’t be suitable.

How it’s held in place

The design uses top-and-bottom clamps that grip the desk legs so there’s no drilling required. This makes installation quick and reversible, which is useful if you’re renting or expect to move furniture. Non-slip pads protect the PC case from scratches and interference during everyday use, but you should still ensure the clamp’s grip is solid and that there’s no wobble.

Build quality and practical use

Constructed from heavy-duty steel, the mount is designed to support up to 44 lbs (20 kg). The open-frame layout improves airflow around the PC, which can help with cooling in warmer environments or during longer use. In practice, this setup keeps the case elevated, making it easier to vacuum and maintain the space beneath the desk.

What stands out in day-to-day use

If you prioritise a tidy, dust-reduced workspace and want to keep a PC off the floor, this can be a sensible option. The absence of drilling is a clear plus for renters or those who don’t want to commit to desk alterations. The trade-off is that this solution is fixed to desk legs of a very specific size, so measurement accuracy is essential.

Limitations and when it may not be ideal

If your desk legs aren’t 65×45mm, or if your PC is wider than 9.84" (250mm) or deeper than 19.68" (500mm), this mount is unlikely to fit. Also, while the clamp design reduces movement, you still should check the stability if the desk surface flexes or if the PC is moved often. It’s not a universal mounting solution and won’t replace dedicated wall mounts or other chassis-support systems for all setups.

What to check before ordering

• Confirm desk leg size exactly matches 65×45mm.
• Measure your PC tower width and depth to ensure it falls within 145–250mm wide and up to 500mm deep.
• Check that there’s adequate counterbalance or space under the desk to accommodate the open-air design.
• Verify there’s no interference with cables or adjacent hardware.

Practical use case example

Imagine a standing desk setup in a small home office. The PC sits securely on the under-desk mount, freeing desk space for a clean monitor and a keyboard tray. With easy access for maintenance and dust-free placement, you can sweep around the desk more easily and keep the floor clear of clutter.

FAQ

Q: Will this mount fit my desk if I have cable management attachments on the legs? A: If the leg dimensions match 65×45mm and there’s room for the clamp, it should still work, verify that cable routing isn’t obstructed. Q: How hard is installation? A: It’s designed to be simple with clamp-on installation and no drilling required. Follow the included steps for a secure fit. Q: Can I remove and relocate it easily? A: Yes, since there’s no drilling involved, you can detach and relocate the mount as needed.

Is it worth it?

It makes sense if you value a cleaner under-desk area, want to protect the PC from dust and moisture, and need a no-drill solution for a desk with 65×45mm legs. If your desk or PC dimensions differ, you’ll likely want to skip it in favour of a different mounting approach.
